Waveguide coupler iyi imagwiritsidwa ntchito makamaka pa bandpass filteloop komanso yofananira ndi njira zazifupi zolumikizira mizere yopatsira. Coupler iyi imatha kusamutsa mphamvu zama pafupipafupi kuchokera ku chingwe chimodzi kupita ku china, potero kukwaniritsa kulumikizana kwamitengo.
Mfundo yogwirira ntchito ya waveguide loop coupler makamaka imadalira mbali ziwiri: makhalidwe opatsirana a loop coupler ndi microstrip line.Directional coupler imatanthawuza chogawa mphamvu ndi njira.
Kuphatikizika kwa annular kumeneku kumakhala ndi malupu awiri oyandikana ndi theka, ndi theka limodzi lokhala ngati doko lolowera ndipo theka lina limakhala ngati doko lotulutsa. Chizindikiro chokwera kwambiri chikafika polumikizana ndi annular motsatira doko lolowera, chimaperekedwa kumtunda woyandikana nawo. Panthawiyi, chifukwa cha kukhalapo kwa maginito, chizindikirocho chidzaperekedwanso ku gawo lina la theka, potero kukwaniritsa mphamvu yogwirizanitsa. Pamapeto pake, ndizotheka kugwirizanitsa chizindikiro cholowetsa kuchokera ku doko lolowera kupita ku doko lotuluka pomwe enuloop yolumikizana bwino kwambiri.
Zizindikiro zazikulu zogwirira ntchito za ma measuloop directional couplers zimaphatikizapo ma frequency ogwiritsira ntchito, digirii yolumikizira (kapena kusintha kwakusintha), mayendedwe, ndi chiwongolero cha mafunde / zotulutsa.
1. Digiri yolumikizira imatanthawuza chiŵerengero cha decibel cha mphamvu yolowetsa ya chigawo chachikulu cha waveguide ku mphamvu yotulutsa ya doko lolumikiza pansi pa chikhalidwe chofanana ndi katundu pa doko lililonse.
2. Kuwongolera kumatanthawuza chiŵerengero cha decibel cha mphamvu yotulutsa mphamvu ya doko logwirizanitsa ndi mphamvu yotuluka pa doko lodzipatula pansi pa chikhalidwe chofanana ndi katundu pa doko lililonse. Ma Directional couplers amagwiritsidwa ntchito kwambiri poyesa ma signature pakugawa mphamvu ndi kuyeza kwa ma microwave.
Qualwaveimapereka ma burodibandi ndi ma high power single directional loop couplers osiyanasiyana kuchokera ku 2.6 mpaka 18GHz. The couplers chimagwiritsidwa ntchito ambiri ntchito.
